It is not easy to confront people with the truth. However, if your want to help people grow spiritually, you need to confront those things that may be blocking their progress. Some blocks to spiritual progress are unforgiveness, fear, lack of wisdom, anger, resentment, or unbelief.
Of course, there are many more blocks to spiritual progress. My Holy Spirit has the job of conforming you to My image, but this is a lifetime assignment.
My body on Earth needs to do more than just exhort one another to love and good works. They also need to rebuke and reprove. I have given My Word to instruct, correct and reprove believers. When you rebuke or reprove a fellow believer, exhort them to abide in Me, abide in My love, and abide in My Word. Then keep praying for them to be open to allowing My Spirit to conform them to Me.
